Underrepresentation of bats in Africa's protected areas. [PDF]
Abstract Biodiversity is severely threatened globally, with habitat loss and other human pressures accelerating species extinctions. Protected areas (PAs) are a critical conservation tool; however, their effectiveness in safeguarding many taxa, such as bats, remains unclear.

Exploring gaps, biases, and research priorities in the evidence for reptile conservation actions. [PDF]
Abstract With over 21% of reptile species threatened with extinction, there is an urgent need to ensure conservation actions to protect and restore populations are informed by relevant, reliable evidence. We examined the geographic and taxonomic distribution of 707 studies that tested the effects of actions to conserve reptiles synthesized in ...

Community Assembly Mechanism of Woody Plants at Different Successional Stages in Karst Areas Based on Functional Traits and Phylogeny. [PDF]
This study reveals a shift in woody plant community assembly from competitive exclusion in early succession to habitat filtering in later stages within karst areas. Environmental distance (80.54%) contributed significantly more than geographical distance (9.95%), providing strong quantitative evidence that niche processes, particularly habitat ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological communities are stressed by rapid and complex anthropogenic changes, threatening the persistence of biotic interactions and ecosystem functioning. Plant–pollinator communities, for instance, undergo structural transformations as a result of land‐use change ...

The underappreciated roles of fog and dew on vegetation and biocrusts
Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

Proteomics and Expression of Immunity Related Genes Research in Fujian Oyster Under the Stress of Iron Salt and Vibrio Parahemolyticus [PDF]
牡蛎隶属于软体动物门(Mollusca)、双壳纲(Bivalvia)珍珠贝目(Pterio)。牡蛎具有很高的食用价值,现已成为中国乃至世界养殖产量最大的经济贝类。然而牡蛎养殖业面临着种种威胁,其中包括了病原体的感染。 铁是脊椎动物血红蛋白的重要组成成分,对机体免疫机制也具有重要作用。但铁对无脊椎动物免疫系统的影响鲜有研究。本论文以福建牡蛎为实验物种,以牡蛎的血淋巴和鳃为实验材料,选择铁盐为胁迫方法和诸多分析技术研究铁盐对牡蛎血淋巴和鳃产生的的影响。 本文采用3mg/L的铁盐胁迫牡蛎96小时 ...
